Chirpstack Multicast Configuration = 633 + 634 + 635 +== 9.1 Introduction == 636 + 637 +ChirpStack has support for creating multicast-groups to which devices can be assigned. When enqueueing a downlink payload for a multicast-group, ChirpStack will analyze which gateways must be used for broadcasting to cover the complete multicast-group. This means that potentially, a single multicast downlink payload will be emitted multiple times. 638 + 639 +Multicast can be used for the following device-classes: 640 + 641 +* Class-B 642 +* Class-C 643 + 644 +== 9.2 Example to configure chirpstack Multicast == 645 + 646 + 647 +This section illustrates how to configure ChirpStack Multicast.
